What Size do I Need
1. Hoops:
Generally speaking, the common rook ring size range from 6 mm to 8 mm in 16g. 6 mm can be comfortable but snug. If your rook was pierced higher up, you may need a bigger hoop. However, asking a professional piercer to measure your piercing is always highly recommended.
2.Bars:
Rook piercings require a curved barbell due to the way they are pierced. The lengths usually range from 6 mm to 8 mm, depending on your skin thickness. For a short and snug fit that tucks the underneath of the barbell away, I recommend a 6 mm length. However, the most safest way is to ask a professional piercer to measure your rook size.
